Yesterday’s physics Nobel went to Francis Halzen for IceCube and high-energy astrophysical neutrinos. Thousands of sensors deep in Antarctic ice detect light associated with rare particle interactions. The project opened an astronomical channel that can preserve directional information from energetic sources, while relying on a large collaboration and decades of patient infrastructure. The academy’s announcement · NSF on the detector.
IceCube’s results have included evidence from an active galaxy and the Milky Way; its record spans a sequence of discoveries. Wisconsin’s account. Today’s chemistry announcement is scheduled no earlier than 10:45 a.m. London. Prize calendar.
